STOVE- SPECIFICATION forming part of Letters Yatent No. 421,564, dated February 18, 1890.

Application filed October 29,1889.

plumbago mixed with fatty material that it will adhere to iron which has been burned or I r oxidized even when the latter is again heated,

will not easily burn off, emits no odor upon the application of heat, and will prevent dust from flying when it is applied to metal. l

sometimes add black oxidenLmgg ggpgge o zolgwylimg C0101".

I have fou" 'd the following proportions of materials to produce the best results, though they may be considerably varied, namely: forty-six gallons of water two gallons of 25 cate of soda, sixty pounds of crude plumbago one gallon of g1 cerine and twelve poun s 0 black oxide of man 'anese if the latter is used. in preparing this polish it will be found best to dissolve the silicate of soda and the Seria1No.828,557. (Nospecimena) r "S glycerine in about five gallons of hot water 30 and afterward to add the plum ago, v1e black oxide of manganese, if it is used, and the rest of the water either cold or hot, all in t 1e quantities an; weig 1 s a ove named. The plumbago and black oxide of manganese 3 5 do not unite with the other ingredients of the compound, and are therefore best added after the soluble silicate of soda and the glycerine have been dissolved. The mixture in all cases, whether the black oxide of man- 40 ganese is used or not, is intended to be shaken before application.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is 5 1. The composition of matter or stove-polish, consisting of water, silicate of soda, and crude plumbago, combined with glycerine, substantially as and for the purpose set forth.

2. The composition of matter or stovepol 5o ish, consisting of water, silicate of soda, crude p lumbagmand glwe, com with black oxit e of manganese substantially as and for the W.
